Answer:
Then, the area is 222,48 in
Step-by-step explanation:
The area of the regular polygon is: 1/2 x perimeter x apothem.
The perimeter 6 times the number of sides of the polygon which is 9*6in = 54 in.
The apothem is: s/2tan(180/n) where "s" is the lenght of the side and "n" the number of sides.
apothem = s/2tan(180/n) = 6in/(2tan(180/9)) = 8.24 in
Then, the area is: 1/2 x 54 in x 8.24 in = 222,48 in
Yes, this can happen if the rectangles are the same dimensions, BUT NO if the dimensions are different.
Answer: 3.5 hours
Step-by-step explanation:
68 + 62 = 130
455 / 130 = 3.5
Hope this helps you! :)
(x+1)(x-4)-(x-2) = 0
x²-4x+x-4-x+2 = 0
x²-4x-2 = 0
/\ = (-4)² - 4*1*(-2)
/\ = 16 + 8
/\ = 24
x = (-(-4)+/- \/24) / 2
x = (4+/-\/4*6)/2
x = (4+/-2\/6)/2
x = 2+/-\/6
x' = 2+\/6
x" = 2-\/6
